AIR-HEATING-l COOK-STOVE.

Specification of Letters Patent No. 12,913, dated May 22, 1855.

To all whom/it may concern:

Be it known that I, CHARLES B. Lovn- LESS, of Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Improvement in Air-Heating Cooking Stoves or Ranges; and I do hereby declare that the same is fully described and represented in the following specification and the accompanyingdrawings, letters, figures, and references thereof.

Of the said drawings, Figure 1, denotes an end elevation of my improved stove. Fig. 2, is a vertical, central and transverse section of it. Fig. 3, is a vertical section of it, the same being taken through the middle of the oven and at right angles to the direction of the section of Fig. 2. Fig. 4, is a horizontal section of it taken through the oven. Fig. 5, is a horizontal section of it taken through the hot air chamber under the oven. Fig. 6, is a vertical and longitudinal section of the smoke flue just in rear of the vertical hot air chamber at the back of the oven.

In the said drawings, A, represents the fireplace; B, the oven which is elevated above the fire-place and arranged in rear of it as seen in the drawings. Underneath the oven there is a drying or hot air chamber C, there being between the bottom plate of the oven and said hot air drying chamber two flues or passages D, E. The flue or space, D, is continued down in front of the chamber, C, and directly between it and the fire place, A. It is also made to extend around the two ends of said fire-place where it is provided with vertical inlets or slots as seen at F, F, in Figs. 1, and 5. Into these inlet passages, F, F, cold air from'the external atmosphere is suffered to pass and from thence to circulate against the ends and the rear side of the fire-place. It thence passes directly over the chamber, 0, and upward (by means of a small pipe, 6,) into a vertical, narrow hot air chamber, G, which is disposed in rear of the oven, B, and with a flue space, H, between its front side and the oven. The top of the chamber, G, is provided with one or more exit pipes as seen at, a, such pipes being for the conveyance of heated air to any room or apartment to be warmed by it.

Between the hot air passage, D, and the oven, B, is the space, E, before mentioned, such space being the smoke flue, which leads directly from the fire place, A, and is made to open into the flue, H. It also freely communicates with a flue space, I, disposed directly in rear of the hot air chamber, G, such communication being made directly underneath the hot air chamber, G, and provided with a damper K, by which it may be cut off as occasion may require. Directly over the whole top of the oven there is another flue space, L, which opens into a flue space, M, that continues down the entire front side of the oven and is made to open into a flue space, N, carried against the entire rear end of the oven and by the rear end of the chamber, G, and made to open into the flue, I, that is in rear of the hot air chamber, G. By means of an inclined partition, O, the flue space, I, is divided so that the smoke passing through is made first to course downward toward the bottom part of the chamber, G, and thence upward toward the top part of said chamber, Gr, escaping out of the pipe, S, that leads out of the said flue space, I.

In its course from the fire place the smoke is made not only to circulate in contact with the four sides and rear end of the oven but it passes in contact with both sides of the hot air chamber, G, and also in contact with the hot air flue, D, communicating heat not only to such oven, but to the air flue and chamber and in its passage by the oven or around the four sides of it, the smoke rushes transversally over them, the oven being placed directly in rearof the fire-place and not on one side of it as is the case in some cooking ranges and particularly so in that of the patent of George S. G. Spence granted on the fourth day of October A. D. 1853. In said Spences range the flue space in rear of the vertical air chamber communicates freely with or opens directly into that in front of it and forms with it one flue space, whereas such is not the case in my invention as they are in fact separate flue spaces which are closed from one another by means of a damper as above described, and the volatile products of combustion do not pass from one directly into another, but the rear flue, I, either receives them from the flue, N, or from the flue, E, the damper closing up the flue H, when it is open, so as to permit the smoke to pass from the flue, E, directly into the flue, I.

I do not claim the arranging a narrow hot air chamber in rear of an oven and so that the flues, which conduct the smoke to the rear part of the oven, shall also carry it into contact With one or both of the op posite sides of the said hot air chamber; nor do I claim the combination of hot air fixtures or flues with the heating and culinary apparatus of a ooking range or stove, because such a combination is Well known and has been used for many years; nor do I claim merely arranging hot air flues, smoke lines, and one or two ovens, so that the smoke, While passing in Contact with the hot air pipes or flues may also pass against the three or four sides only of either one or both ovens; but

WVhat I do claim is My improved arrangement of one continuous smoke flue around an oven and against hot air flues arranged as described,

whereby not only are the hot air flues and four sides of the oven subjected to exposure to the heat of the smoke While coursing through such continuous flue, but that the end of the oven and the end of the vertical hot air chamber, G, are also exposed to be so heated, my invention being an important and useful improvement on the general combmatlon and arrangements of hot alr and culinary fixtures herein referred to and described.

In testimony whereof I have hereunto set my signature this fifth day of May A. D.
